How to unlock Heroes in XCOM: Enemy Unknown

Using certain soldier names in XCOM: Enemy Unknown will activate XCOM Heroes - pre-designed super soldiers such as Sid Meier and Ken Levine. Before activating a Hero, a pop-up will warn you that they're too damn amazing to allow you to continue the game with achievements turned on, and you cannot modify a Hero character after summoning it. If you decide to use one, do avoid killing him with some bull-headed tactical screw-up -- we'd kind of like BioShock Infinite to be finished.
